CONTINUOUS ROLLING-MILL.

SPECIFICATION forming part of Letters Patent No. 328,591y dated October20, 1885. Application filed April 13, 1885. Serial No. 162,019. r(Nomodel.)

To all whom t may concern.-

Be it known that I, 'EDWIN S. LENGX, a citizen of the United States,residing at Vorcester, in the county of Vorcester and State ofMassachusetts, have invented certain new and useful Improvements inRolling- Mills for Bolling IVire Rods 5 and I declare the following tobe a description of my said invention sufficiently full, clear, andexact to enable others skilled in the art to which it apperiains to makeand use the same, reference being had to the accompanying drawings,which form a part of this specification.

The object of my present invention is to provide a rolling-mill formaking wire rods that will produce small-sized rods at a single heat,and in which the rod at the latter portion of the mill will be carriedand reduced surely and rapidly and without liability of forcing themetal in a manner that will produce fins upon the rods. This object Iattain by an apparatus in which the leading portion of the mill iscomposed of series of rolls operating in pairs, for breaking down thebar and extending its reduction to a stage where the rod is of a size ofabout No. 5 wire gage, while the latter portion of the mill,for furtherreducing the extenuated rod,is composed of sets of rolls arranged tooperate as triplets, or three or more rolls in each set. The particularsubject -matter claimed is hereinafter definitely specified.

In the drawings I have represented different arrangements of wire-rodrolling-mills, illustrating the manner in which my invention may beapplied to use, and which modifications I include as within the scope ofmy said invention.

Figure l is a plan view of so much of a wire-rod rolling-mill as willillustrate the nature of my invention. Fig. 2 is a vertical longitudinalsection of the same. Fig. 3 is a diagram illustratinga modification inthe arrangement of the latter portion of the mill. Fig. 4 is a diagramshowing another modification,in which anintermediate double-inclinedover-feed table is employed. Fig. 5 is a view illustrating thearrangement of the triple rolls.

In my improvement the first part of the mill consists of a series ofrolls, c to c", arranged in pairs for operating in the order commonlyknown as a continuous rollingmill. In this train ten pairs of rolls(more or less) may be employed, which are grooved for effecting thereduction of the bar or billet from a diameter of about one and one-halfinch to a partially-formed wire rod of about No. 5 wire gage, more orless. At this stage of the reduction I change the construction andarrangement of the mill and employ for the further reduction andfinishing of the rod series or sets of rolls, which are arranged intriplets, or with three or more rolls operating upon the rod at the sameposition. Of these triplet rolls I preferably use four sets, although agreater or less number of such sets may be used, if desired, inconnection with the lead-` ing train of rolls arranged in pairs. Thesets of triplet rolls may be combined with the leading continuous trainof rolls c to c, either as shown in Figs. 1 and 2, to operate as acontinuous mill, and directly following said pairs of rolls, or the millmay be arranged as shown in Fig. 3, the sets B B B2 B3 of triplet rollsbeing arranged in the order known as the Belgian mill, or with the setsdisposed in lateral right and left arrangement, as indicated, so thatrods as they issue from the leading continuous train Amay be alternatelyled through the triplet sets, one to the right and the next to the left;or, again, the mill may be constructed as indicated in diagram Fig.d-viz., with a primary train of rolls, A, arranged in pairs incontinuous7 order, followed by two or more supplemental trains, C, ofrolls, f, g, and h, arranged three or morein a set, such triplet setsbeing disposed for operating in continuous order throughout the trainsC, and with an intermediate guideway, D, and a double-inclined platformor table, E, for accommodating the over-feed of the rod between theprimary and supplemental trains; also with a suitable shifting guide orswitch, D, for directing the rods of either of the trains C.

The supplemental train may be located at the foot of the over-feed tableor platform, and said table may be laterally inclined; or saidsupplemental trains may be disposed at the ICO right and left of saidtable at the position indicated by the lines O2, or in any otherconvenient position, as desired.

The housings for mounting the rolls and the driving-gearing forimparting motion thereto may be arranged in the manner usually employedfor rolling-mills or in any practical convenient manner.

In Fig. 5 I have illustrated one method in Which the triplet sets ofrolls may be mounted or set up for operation when the sets are arrangedin the order of a Belgian mill. The several roll shafts are gearedtogether, as at I, the horizontal shaft being connected by gears j k lmWith a driving-shaft extending along the lower part'of the frame foroperating each of the four sets of rolls. For continuous order thebearings of the several triplet rolls might be supported on frame-Workextending longitudinally of the mill.

In the operation of my present form of rolling-mill the heated billet isdrawn from the furnace F, and passed through the train A and through theseveral sets of triplet rolls, B, to its nal completion Without stoppingor reheating thc rod.

Among the advantagesincident to my invention it vmay be mentioned thatsets of rolls operating as triplets, or with three or more rolls in aset, carry the small rods in a better manner than do pairs of rolls,While they e'ect a more rapid reduction of the rod with less liabilityof forming fins thereon. Such triplet sets of rolls also permit oftherod being carried through faster, so that there is less liability of thesmall extenuated rods losing their heat before they are completed orclear of the final finishing-rolls.

I am au' are that rolling-mills have heretofore been constructed inWhich a primary train operating in continuous order, supplemented bysets of rolls operating in Belgian order, have been employed, and I donot, therefore,

make claim, broadly, to such-feature, except the supplemental series ofrolls are mounted in sets of three or more, eaehacting simultaneouslyupon the Wire rod. Neither do I herein make claim to the feature of aprimary continuous train supplemented by one or more finishing trains,except the rolls are mounted to operate in triplet sets simultaneouslyacting at one position upon the wire rod.

What I claim as of my invention, and desire to secure by Letters Patent,is-

- 1.- In an apparatus for rolling Wire rods, the combination of a trainof rolls operating in pairs, and one or more sets of rolls, each setconsisting of three or more rolls,the respective faces of whiehtogetherform the reducing pass of said set, said trains of rolls being disposedfor operating in a continuous and supplemental manner, as set forth.

2. A rolling-mill for making Wire rods, having a leading train of rolls,A, arranged in pairs for breaking down and partially reducing the rod,supplemented by a set or sets of rolls, B, arranged to operate astripletsA for completing the reduction and imparting the finished formand size to the rod, substantially as set forth.

3. In a rolling-mill for making Wire rods, the combination of a leadingcontinuous train of rolls arranged in pairs for breaking down andpartially reducing the rod, and a supplemental 'set or sets of rolls, B,each set consisting of three or more rolls, for completing thereduction, disposed for finishing the rod in a consecutive manner and ata single heat, as set forth.

Witness my hand this 7th day of April, A. D. 1885.
